electric signals into optical signals. The optical signals emit
from the first light emitting members 142 toward the corresponding
first converging lenses 1415. The optical signals enter the first
optical coupling member 141 through the first converging lenses
1415 and are reflected by the first reflective surface 1413 toward

fourth converging lenses 4126 and are reflected by the second
reflective surface 4123 toward the corresponding third converging
lenses 4125. The optical signals emit from the second optical
coupling member 412 through the corresponding third converging
lenses 4125 and toward the second light receiving member 416. The
second light receiving member 416 converts the optical signals into
electric signals and transmits the electric signals to the second
circuit board 418. The multimedia display device 400 feeds back
electric signals to the second circuit board 418. The second
circuit board 418 converts the electric feedback signals into
optical signals. The optical signals emit from the second light
emitting members 414 toward the corresponding third converging
lenses 4125. The optical signals enter the second optical coupling
member 412 through the corresponding third converging lenses 4125
and are reflected by the second reflective surface 4123 toward the
corresponding fourth converging lenses 4126. The optical signals
emit from the second optical coupling member 412 through the
corresponding fourth converging lenses 4126 and enter the aligned
second optical fibers 34. The optical signals transmit along the
corresponding second optical fibers 34 toward the corresponding
second converging lenses 1416. The optical signals enter the first
optical coupling member 141 through the corresponding second
converging lenses 1416 and are reflected by the first reflective
surface 1413 toward the corresponding first converging lenses 1415.
The optical signals emit from the first optical coupling member 141
through the corresponding first converging lenses 1415 to the
aligned first light receiving members 143. The aligned first
receiving members 143 convert the optical signals into electric
signals and transmit the electric signals to the data source 300
through the conductive member 16.
